What is a Puller?

Pull cylinder is a technical term for car repair. Engine cylinder pulling refers to obvious longitudinal mechanical scratches and abrasions on the inner wall of the cylinder within the range of motion of the piston rings. In severe cases, fusible wear occurs, resulting in difficulty in starting the engine or self-extinguishing failure.

Generally, it refers to the abnormal adhesion and melt marks of cylinder walls, pistons and piston rings, and is a general term for cylinder failure.

Pulling cylinders is a major engine failure. The fundamental reason for pulling the cylinder is that it is difficult to form an oil film between the cylinder inner wall, the piston ring and the piston, resulting in poor lubrication and even dry friction.

The so-called "pulling cylinder" refers to the inner wall of the cylinder being pulled into a deep groove, and the piston, piston ring and cylinder wall friction pair lose their sealing, resulting in the reduction of cylinder compression pressure and power loss; The downward channeling of the combustible mixture will increase the pressure of the crankcase, and in severe cases, it will cause the crankcase**; Lubricating oil escapes into the cylinder, causing oil burning; Smoke from the exhaust pipe is severe; Abnormal engine noise; The engine did not work properly and even stalled.

Cylinder pulling refers to the phenomenon that the engine piston or piston ring pulls the cylinder working surface into a scar, resulting in the loss of the sealing performance of the friction pair between the piston, the piston ring and the cylinder wall.

Symptoms of pulling cylinders.

1. The compression pressure of the cylinder is reduced, and the power is lost;

2.The downward channeling of the combustible mixture will increase the pressure of the crankcase, and in severe cases, it will cause the crankcase**;

3.Lubricating oil escapes into the cylinder, causing oil burning;

4.Smoke from the exhaust pipe is severe; Abnormal engine noise; The engine did not work properly and even stalled.

What causes a cylinder?

The engine cooling system is overheated due to water leakage and water shortage, and cannot be replenished in time; The piston ring is broken and scratches the cylinder wall; The piston ring falls off and scratches the cylinder wall; Because the piston ring is stuck in the ring groove due to carbon deposits, it loses its sealing effect; The piston came out and scratched the cylinder wall; Foreign matter enters the cylinder; The gap between the piston and the cylinder wall is too small; The tight assembly of the piston leads to the deformation of the piston; The piston is severely deformed or burned; Long engine time, high speed or overload, etc.

What if the cylinder is pulled?

When the engine fails to pull the cylinder, in the upper part of the middle part of the engine, a click of the piston against the cylinder can be heard, similar to the sound when the piston is slightly loose. The noise of cold cars is obvious. As the engine temperature increases, the noise decreases, but not significantly.

If you increase the oil and gas door, the noise will increase as the engine speed increases.

If a pull cylinder is found, the cylinder head should be removed, the strain on the cylinder wall should be checked, and the cause of the strain should be found. If there is only a slight deformation due to the tight fit between the piston and the cylinder wall, the cylinder wall can be slightly ground and then reinstalled with the original piston. If the strain is severe, the cylinder should be re-bored and replaced with an enlarged piston, which is the same as the repair method of the cylinder**.

In fact, it is difficult for the engine cylinder to form an oil film in the engine cylinder, resulting in poor lubrication and heat dissipation between the piston and the cylinder, resulting in dry friction. Therefore, regular oil change and regular maintenance are very important. If the oil is not changed for a long time, the cylinder will be pulled.

Engine cylinder pulling refers to the obvious longitudinal mechanical scratches and scratches on the inner wall of the cylinder within the range of the moving leather of the piston ring, and in severe cases, melt wear occurs, resulting in the difficulty of engine start or self-extinguishing fault. Pulling cylinders is a major accident in the engine.

The fundamental reason for the concession of the cylinder is that it is difficult to form an oil film between the inner wall of the cylinder, the piston ring and the piston, resulting in poor lubrication and even dry friction. There are a number of reasons for this.

The inner wall of the cylinder is drawn into a deep groove, and the piston and piston ring lose its tightness when rubbing against the cylinder wall, resulting in a decrease in the compression pressure of the cylinder and a loss of power. In severe cases, melt wear occurs, causing the engine to start difficult or self-extinguishing failure. Pulling cylinders is a major event for the engine.

The fundamental reason for pulling the cylinder is that it is difficult to form an oil film between the inner wall of the cylinder, the piston ring and the piston, which causes poor lubrication and even dry friction.

The main reason for the engine cylinder is that the water tank is seriously lacking in lead and the water engine has abnormal high temperature, and it has not been found and dealt with in time. When the piston works up and down at high speed, a large amount of heat is generated and transmitted to the cylinder liner. The abnormal rise of water temperature and poor heat dissipation of the cylinder liner aggravate the expansion of the piston, causing the gap between the piston and the cylinder liner to become smaller and smaller, and finally cause friction.

Pistons, piston rings and cylinder liners are poorly lubricated and cause dry friction. For example, the main oil channel lubricating oil nozzle is blocked or the installation angle is incorrect, and the engine lubricating oil is insufficient.

Engine pulling cylinders, sticking cylinders, etc., are major injuries that require overhaul of the engine。Nowadays, it may be better to overhaul the engine block than to replace the engine directly. Therefore, accidents like this kind generally do not occur in our normal use and maintenance of cars.

However, knowing a little more about the car and its heart that we normally use and rely on will be more helpful for us to use and maintain it properly.

One cylinder of the engine works in much the same way as the syringe we usually seeThere are also cylindrical cylinders and pistons. The cylinder block of the car is made of steel, and although the piston is made of aluminum alloy, it has several piston rings on it, and this piston ring is a steel ring. In the operation, the live Huaifan plugging ring is in close contact with the cylinder block, which can make the combustion chamber in the cylinder completely sealed.

In this way, the strong air pressure generated by the combustion of the oil can push the piston downward.

Pulling the cylinder is due to poor heat dissipation, or poor lubrication, or the air entering the cylinder is not clean, etc., so that there are scratches on the cylinder wall。It is equivalent to a scratch on the inner wall of the syringe tube, which makes a gap between the piston and the tube wall, and such a syringe may not be able to inject water columns. When the cylinder appears, the air tightness of the combustion chamber is not good, and the power output of the engine decreases.

Severe overload in the car, long hours of heavy load work. It is easy to cause piston fatigue fracture and cause cylinder pulling.

When the piston is wide and the piston ring is reciprocating in the cylinder, the cylinder is forcibly pulled out of obvious scratches and grooves due to poor lubrication or too small mutual clearance.

It means that the piston ring in the engine cylinder has longitudinal scratches or scratches on the cylinder wall due to the lubricant, and the friction inside is relatively large when it is active.

The boiling is the cooling of the engine, which may be due to a lack of water or a leak in the closure, or the fuel consumption is too large, or it may be an overloaded operation.
